Description
Technical field
The utility model belongs to Automobile drive vehicle bridge field, and in particular to a kind of light-weighted differential assembly structure.
Background technique
Domestic automobile drives in vehicle bridge, and four planetary gears is mostly used to be offset to the differential assembly knot of differential right casing
Structure.In differential assembly, driven wheel of differential uses central through hole (inside that central through hole is located at screw thread distribution hole) and differential mechanism
The male half coupling of right shell, which cooperates, to be positioned, and the positioning spigot of differential mechanism left housing and differential right casing is located at the inside of differential assembly.This
Kind structure, the seam allowance to realize between driven wheel of differential and differential right casing position, and increase the centre bore weight of driven wheel of differential
Amount, increases the male half coupling weight of differential right casing；Seam allowance to realize between differential mechanism left housing and differential right casing positions, and increases
The male half coupling weight for having added differential mechanism left housing increases the right shell inner stopper processing cost of differential.
Summary of the invention
The utility model is to solve in Automobile drive vehicle bridge, due to using central through hole and differential mechanism using driven wheel of differential
The male half coupling of right shell cooperates positioning, is located in differential assembly using the positioning spigot of differential mechanism left housing and differential right casing
Portion, cause driven wheel of differential weight increase, differential mechanism left housing weight increase, differential right casing weight increase, differential assembly at
The problems such as this increase, provides a kind of light-weighted differential assembly structure, reduces weight and cost.
The utility model adopts the following technical scheme that realization:
A kind of light-weighted differential assembly structure, the tooth of driven wheel of differential are placed face down on workbench, and differential mechanism is right
The outer diameter of axle of shell is with the cooperation of the inner stopper of driven wheel of differential and end face is bonded；The inner stopper of differential mechanism left housing and differential right casing
Outer diameter of axle cooperation and end face fitting；After the screw thread distribution hole of screw bolt passes differential mechanism left housing and differential right casing, screw in from
The tapped blind hole of dynamic bevel gear simultaneously tightens fixation.
Further, the inner stopper structure of the driven wheel of differential is located at the outside of screw thread distribution hole.
Compared with prior art the beneficial effects of the utility model are:
By the way that the positioning spigot of driven wheel of differential, differential mechanism left housing to be placed in the outside of distribution hole, it is total to reduce differential mechanism
At weight and cost.Specifically: by increasing the centre bore of driven wheel of differential, reduce the weight of driven wheel of differential；By taking
Disappear the male half coupling structure of differential right casing, reduces the weight of differential right casing；By cancelling in differential right casing open end only
Mouth structure reduces processing cost；By cancelling the inner stopper structure of differential mechanism left housing, the weight of differential mechanism left housing is reduced.
Detailed description of the invention
The utility model will be further described below with reference to the accompanying drawings:
Fig. 1 is a kind of light-weighted differential assembly topology view of the utility model；
Fig. 2 is the utility model driven wheel of differential view；
Fig. 3 is the utility model differential right casing view；
Fig. 4 is the utility model differential mechanism left housing view；
In figure: 1. driven wheel of differential, 2. differential mechanism left housings, 3. bolts, 4. differential right casings
Specific embodiment
The present invention is further elaborated in conjunction with attached drawing.
As shown in Figure 1, a kind of light-weighted differential assembly structure, the tooth of driven wheel of differential 1 are placed face down on workbench
On, the inner stopper cooperation (outside that inner stopper is located at screw thread distribution hole) of the outer diameter of axle of differential right casing 4 and driven wheel of differential 1 and
End face fitting；The inner stopper of differential mechanism left housing 2 is with the cooperation of the outer diameter of axle of differential right casing 4 and end face is bonded；Bolt 3 sequentially passes through
The distribution hole of differential mechanism left housing 2 and differential right casing 4 screws in the tapped blind hole of driven wheel of differential 1 and tightens fixation.
As shown in Fig. 2, driven wheel of differential increases centre bore, while guaranteeing the strength of gear teeth, weight is reduced；Using screw thread
Distribution pore structure is spirally connected with differential mechanism left housing 2, differential right casing 4；Inner stopper structure is located at the outside of screw thread distribution hole, with differential
The outer diameter of axle of the right shell of device cooperates positioning.
Positioned as shown in figure 3, differential right casing is cooperated using the inner stopper of outer shaft gauge structure and driven wheel of differential, and with difference
The inner stopper of fast device left housing cooperates positioning；Cancel the former male half coupling structure with driven wheel of differential cooperation, reduces weight；Using point
Cloth borehole structure, for across bolt 3.
As shown in figure 4, differential mechanism left housing is used for using distribution borehole structure across bolt 3；It adopts and is set on the outside of distribution circular hole
Inner stopper structure is set, for cooperating with the outer diameter of axle of differential right casing 4.
